My sister’s perverse request! Loyalty test completely escalates!

I actually didn’t want to go that far! But what could I possibly do? My sister asked me to test her husband’s loyalty. Well, no sooner said than done. I put on a hot outfit to see how far he would go. Well, from the looks of it, he would go VERY far! I simply couldn’t help but treat myself! I had no idea she was so lucky with this cock!! He just fucks me mercilessly!! Could you have resisted?
